Hello !

At first, thanks for your great guide !
I managed to make SL running on my 2,5" External HDD !
Sound, Graphics, W-Lan-LAN, All Cores ... all works !
Now i tried the same steps with my internal 3,5" S-ata drive,
i boots (bootloader works...) and then no sound from the HDD ?!
After a Few Seconds the grey Circle with the Cross appears....
Can anybody help me ?! I tried a few things, but nothing helps

My Hardware:

Intel Q6600
Asus P5K Green
2x1GB OCZ 800mhz Ram
250GB Seagate S-ATA HDD (10.5.8)
250GB Western Digital S-ATA HDD (for 10.6.0)
DVD-Rom Drive (S-ATA)
Working 10.5.8 to install on other HDD !
